Warm Cold Feet in Bed

Although I have the window open for the fresh air when I go to sleep, I personally have to be toasty warm. As the weather is colder now, I put on an extra blanket - but it is too hot. Without the extra blanket, I am OK except for my feet and I wake up all night every time I move them onto a cold spot. I put the blanket only on my feet which keeps them warm and I am able to warm up the area around my feet so there are no cold spots, but the blanket feels uncomfortably heavy. My husband has very warm feet and does not want the blanket on his side, so the blanket occasionally falls off the bed too. What to do?

Idea! I bought a car window screen at the dollar store for the summer. It is rather thin but the silvery side worked great to keep the car cool. I don't need it for the winter so I brought it in, folded it in half (silvery side out) and put it under my sheet at the end of the bed. It reflects my heat perfectly to keep my feet warm. Problem solved!
